Description

[Detailed Description of the Invention] The present invention relates to a device for aligning and guiding waste straw in a bundling section of a combine harvester.

In other words, in the binding section of the combine, which is configured so that the waste straw to be carried out to the rear of the machine is transferred along the deck and tied by the tying machine, the culm sides of the waste straw to be transferred along the deck can be aligned. It also provides good support without causing the culm side to protrude in the bundled state and is bundled unevenly. After binding, it can be released smoothly, and it can be bundled and released reliably and well without disturbance, so that it can be carried out suitably. It is something to do.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the combine harvester, with a reaping section B at the front of the machine body supported by crawlers 5 and a threshing section C at the rear.
is installed, and above the rear cover part 6 in the rear part of the threshing section C is a straw removal chain 9 that inherits the straw 8 from the foot chain 7 and conveys it rearward, which is inclined with respect to the longitudinal direction of the machine. Extend and configure.

A binding part is installed inside the cover 10 attached to the rear of the rear cover part 6, and the binding machine A in the binding part has a binding case 11 having a square-shaped recess 11a facing diagonally upward.
3, including the packer 12, needle 13, door 14, etc.
1 part and 32 parts such as the binding part 15 and the discharge arm 16 are supported and driven.

At the rear of the rear cover part 6, a support frame 17 and a support frame 17' are installed horizontally at the upper front side and at the lower rear side, respectively, and a movable support frame 17 and 17' is installed movably along both support frames 17 and 17'. The binding case 1 is attached to the frame 18.18'.
1, and both decks la and lb spanning 31 parts on the side of the binding case 11 are tilted and both ends of each are connected to the moving frame 18. A shutter 19 to be energized is installed to be able to rise and fall freely, and a spring rod 20 for guiding and supporting, which is supported from the binding case 11 side, is installed above the deck 1a in the same way.

Further, the binding case 11 is installed so that power can be transmitted from the transmission case 21 side via the telescopic transmission part 22,
A telescoping rod 25 is interposed between the machine frame 23 and the binding case 11, and is extendable and retractable by a handle 24, so that the binding machine A and the decks la, lb, etc. can be adjusted in movement.

On the side of the deck 1a, a deck 1 that supports the culm side of the waste straw 8 and guides it downward is inclined and has support frames 17 at both ends.
．． 17', culm base aligning plates 2 that extend over the 2nd side of the deck 1 and can contact and align the culms of the waste straw 8 are installed so as to stand up against the upper surface of the deck 1. However, a short cylindrical portion 2a formed at the front end of the culm alignment plate 2
is rotatably fitted to a support shaft 26 that is fixed to the support frame 17 and made to stand upright, and the front end of the tension spring 28 is connected to a support metal 27 that projects forward from the support shaft 26, and the culm base alignment plate 2 The rear end of a tension spring 28 is connected to a bolt 30 which is adjustable and tightened by a nut 29 on the outer surface portion near the front end of the culm base aligning plate 2 so as to be pressed against the tying machine A side by the tensile force of the tension spring 28. and configure it.

In addition, a plate-made culm chassis 3 is pivotally supported at the rear end of the culm alignment plate 2 via a hinge 31, and a spring 4 is interposed in the hinge 31, and the elastic force of this spring 4 is The culm shutter 3 is made to stand up in the same manner as the shutter 19 so that the culm of the waste straw 8 during bundling can be supported by the culm, and when pushed backward by the culm of the bundled waste straw 8', the spring 4 The structure is such that the culm shutter 3 is rotated rearward and opened under tension.

In addition, in the figure, 32 is a binding cord case.

During combine harvester operation, if the straw 8 is a short culm, as shown in FIG. 1a, 1b and flowing down, the culms of the waste straw 8 contact the upright surface of the culm alignment plate 2, which is pressed against the upper side of the deck 1 by the tensile force of the tension spring 28, and flow down while being aligned. Then, on the lower side of the deck, insert the door 14, shutter 19, and ■-shaped recess 11 of the binding case 11.
The culm part of the straw 8 whose culm is supported at the bottom of the straw is supported by the culm shutter 3, and when a certain amount is reached, it is bundled by the binding machine A and is bundled and discharged as shown in Fig. 8. straw 8'
Due to its bundled position, the discharge arm 16 discharges the straw to the rear as shown by the imaginary line, but the bundled straw 8' pushes the culm shutter 3 backward against the spring 4 and opens the shutter 19 in the same way. It is pushed down and released backwards, and then the shutter 9 returns to the state of supporting the next straw 8 again in the same way by the pressure of the spring 4 of the culm shutter 3.

Moreover, if the straw 8 is a long culm, as shown in FIG. The culm base aligning plate 2, which is pushed by the culm base of the long culm flowing down on la and lb, is rotated in the direction away from the deck 1 under tension from the tension spring 28, and the culm of the straw 8 is rotated away from the deck 1. Guide the base to align, and culm shutter 3
It is also possible to support the culm base, bundle and release in the same manner as described above.

Although it is possible to change the binding position of the straw 8 by moving the binding machine A by operating the handle 24, the culm base alignment plate 2 and the culm base shutter 3 operate in the same manner regardless of such adjustment. can be done.

In this way, the present invention allows the straw to be carried out to the rear of the machine to be supported by the deck 1 in a horizontal position, while the culm end is supported by the deck 1.
In the binding section of the combine, which is configured to be brought into sliding contact with the culm alignment plate 2 installed in an upright position and transported to the bundling machine A for tying, the terminal end side of the culm alignment plate 2 is provided with a hinge 31 or the like. A shutter 3 is installed so that it can be fanned in the direction of the straw culm body by the movable attachment part, and the shutter is folded from the culm base alignment plate 2 toward the bundling machine A side by means of a spring 4 interposed in the rotary attachment part. A shutter 19 is elastically biased to a curved culm receiving position, and furthermore, at the lower part of the deck 1a between the shutter 3 and the binding machine A, there is a shutter 19 that can be rotated to open downwardly at the rear of the deck.
a guiding support spring rod 2 which is provided in an upright position with an elastic bias, and whose free end is located near the shutter 19 in the upright position;
0 is installed along the upper surface of the deck 1a, so that the straw is supported in a horizontal position on the deck and transported toward the binding position, and the unevenness of the culm end of the waste straw is corrected and transported. In addition, during transportation, the culm side has a large volume and weight and tends to flow down in advance compared to the tip part, so the straw tends to be in an oblique position. By holding it with the guiding and supporting spring rod 2o installed opposite to this, it is possible to transport the part to be bundled while keeping the orientation of the part against the binding machine out of order, and the waste straw that is accumulated at the binding position is The binding machine is in a state where the alignment and binding machine posture is good, and the binding process can be performed without any mistakes in binding.

Moreover, the waste straw collected at the bundling position is not only supported by the shutter 3 at the base of the culm, but also by another shutter 19 at the middle part of the culm, and by the bundling case 11 at the tip at the same time. This prevents the entire culm from being bent in the middle or at the end, making it possible to achieve better binding. The shutter 19 that supports the middle part is rotated to the bottom of the deck, and the straw held by the shutter 19 is held down by the spring rod 20, whereas the culm support is Since this is carried out only by the shutter 3 that fans outward in the direction of the culm, the culm base, which has a large volume, is ejected first when the bundle is released.
The bundled waste straw is accurately discharged in a circular arc trajectory centered on the tip side, to a position closer to the tip side, that is, a position far from the uncut side of the machine.

Remarkable effects can be obtained.
